PAL - Wearable and Personalized Habit-support Interventions in Egocentric Visual and Physiological Contexts.

Habits are automatic actions in stable contexts and can help sustain behavior change. We created a wearable device, called PAL, to recognize egocentric visual and physiological contexts and deliver just-in-time habit-support interventions using open-ear audio output. PAL supports personalized goals, reminder contexts, and reminder messages, and uses on-device deep learning for privacy-preserving and low-shot context detection to enable self-tracking and context-aware habit-support interventions for behavior change.
